Everyone has been asking for this kit. It gives the
amp a master volume, and an overdrive stage for
tremendous versatility. The clean tone is still
available. Easy, well illustrated instructions
included. Great tone from this newer amp.

The modification involves changing some parts on the circuit board and relocating a couple of leads

The Normal volume becomes the master volume, and the existing Bright channel is the preamp volume.

One jack gives you the standard tone (bright channel) the other activates the new high gain stage for a whole lot more tube-gain. easy to use and great tone.
